Pyoderma Gangrenosum After Abdominal Free Tissue Transfer for Breast Reconstruction: Case Series and Management Guidelines

Postsurgical Pyoderma Gangrenosum Requiring Plastic Surgical Intervention: A Practical Review

Pyoderma gangrenosum is a neutrophilic dermatosis characterized by immune dysfunction and pathergy. Thus, it is frequently seen in patients with underlying systemic illnesses or postoperatively. For the performance of the debridement or closure of the resultant defect, plastic surgeons are often involved in the care of pyoderma patients. However, both procedures may exacerbate the injury. Therefore, plastic surgeons must be familiar with the presentation of postsurgical pyoderma to avoid further damage and safely repair related soft tissue defects. A systematic search of the PubMed/Medline database was performed using the following keywords: "pyoderma gangrenosum" and "surgery." This online database search has identified 656 studies published between 1958 and 2022. Only reconstructed cases of postsurgical pyoderma gangrenosum were selected. Twenty-eight patients who developed pyoderma after dermatologic, plastic, orthopedic, cardiovascular, general, or obstetric surgery were included in this study. The average time to the PG presentation and diagnosis was 5.5 and 17 days, respectively. Diagnostic scoring tools were not used, and the diagnosis was primarily based on histopathology after repeated treatment failures. The patients received split- or full-thickness skin grafts, local, pedicled, and free flaps. An estimated 82.1% underwent skin grafting, whereas 42.9% underwent flap reconstruction. In addition, 21.4% got both the graft and flap. Accurate diagnosis of PSPG, prevention of further surgical injury, and timely medical management are vital for improving patient outcomes. Reconstruction can be performed, if required. However, despite the availability of different reconstructive techniques, there is no standard approach to the management of the PSPG.

Dermatologic Complications Following Cosmetic and Reconstructive Plastic Surgery: A Systematic Review of the Literature

PURPOSE

Plastic surgery procedures, including minimally invasive cosmetic procedures, continue to grow in popularity. Although dermatologic complications following plastic surgery procedures are rare, the authors have encountered several of these complications in their practice, including herpes simplex virus (HSV-1) and varicella zoster virus (VZV) infections, pyoderma gangrenosum (PG), contact dermatitis, and suture hypersensitivity. These cases prompted a systematic literature review of dermatologic complications following plastic surgery procedures.

METHODS

The authors conducted a systematic review of PubMed, MEDLINE, EMBASE, Scopus, Web of Science, and the Cochrane Library to identify relevant articles published from 1975 to 2021. Articles were independently reviewed by the authors to determine whether studies met inclusion criteria.

RESULTS

The majority of articles that met inclusion criteria represented level V evidence. The most robust evidence in the literature was for PG, for which there were 63 total studies. Pyoderma gangrenosum was most frequently reported following breast surgery (85.1%), while HSV-1 infections were frequently seen following minimally invasive procedures (84.6%). VZV reactivation was reported after a range of interventions, including pedicled flap surgeries and laser treatments. Other complications, such as suture hypersensitivity, were less frequently reported in the literature, usually as isolated case reports.

CONCLUSIONS

Dermatologic complications represent a rare but serious concern following plastic surgery procedures. While most dermatologic complications resolve with appropriate treatment, sequelae of these conditions can be devastating to the patient's overall outcome. Plastic surgeons performing procedures at a high risk of these complications should recognize the diagnostic criteria to facilitate appropriate treatment.

Pyoderma Gangrenosum Mimicking Wound Infection after Breast Cancer Surgery

Postoperative pyoderma gangrenosum (PPG) is rare, and its diagnosis is often delayed because of its wound infection-mimicking course. A 53-year-old breast cancer patient who underwent breast-conserving surgery of the right breast presented with fever, leukocytosis, C-reactive protein elevation, and redness of the right breast on postoperative day (POD) 3. The breast wound showed desquamation with painful ulcerative changes from POD 6, and fever was sustained under antibiotic administration. Wound irrigation was attempted; however, inflammatory skin damage progressed to involvement of the entire skin overlying the breast. With clinical suspicion of PPG, skin biopsy and systemic corticosteroid initiation were performed on POD 12. Wound damage progression ceased, and the systemic inflammation subsided. The patient underwent split-thickness skin grafting under intravenous corticosteroid administration, and the wound healed after 30 days. PPG is a rare clinical scenario. Early diagnosis is critical to avoid unnecessary treatment and aggravation of the surgical wound.

The surgical approach to Pyoderma gangrenosum: A retrospective monocenter study

Pyoderma gangrenosum is a diagnosis of exclusion. It occurs rarely and is frequently misdiagnosed. It can result in severe tissue loss, particularly in surgical units with little experience. Nevertheless, surgical treatment might be necessary for reconstruction, once the progression of these wounds is controlled. We aimed to characterize medical findings in Pyoderma patients with extensive defects to assess the surgical procedures and their outcome. A retrospective study was conducted at our centre over an 18-year period. Inclusion criteria were the diagnosis of Pyoderma gangrenosum and at least one surgical intervention. Descriptive statistics were used to analyse the data. Sixteen patients were included. The mean size of the lesions was noted with 12 × 8 cm. Surgical procedures comprised debridements/necrectomies, allograft conditioning, negative pressure wound therapy, skin grafts, and microvascular free flaps. Seven patients were discharged with healed wounds, six with minor wound healing disturbances. Three patients succumbed to their underlying diseases. Drug-based therapy can stop the progress of Pyoderma, but severe tissue loss can be a persistent problem. According to our data, reconstructive-surgical treatments (debridement, autologous and allogenous skin transplantation and microvascular free flaps) act as an integral component of the therapy and can be safe options for selected patients. Furthermore, we provide an algorithm that we follow at our department in severe cases.
